The Klinger set of nine basic crystal structures is a valuable teaching aid for physics and chemistry.
- Hand made in the USA
- Permanent structures
- Made with grade A materials
Similar patterns of atomic arrangement reappear in large numbers of different substances. Three of the six symmetry systems are represented in the set.
Included in the set are calcite, which is rhombohedral, graphite, magnesium, and wurtzite which are hexagonal, sodium chloride, cesium chloride and copper which show full cubic symmetry. Properties of substances as related to crystalline structure are easily visualized from these high quality colorful lattice models. Concept of unit cell, cohesive forces and the meaning of coordination numbers as well as crystal systems can be explained.
Models are assembled with wooden spheres 25 mm in diameter, connected by means of plated steel rods. The wooden spheres designating the atoms, are painted colors depending on the element represented. Linear enlargement is 250 million. Models vary from approximately 18 to 38 cm. in height.
